A look at the Unreleased Trevi Fountain LEGO Set #21020

I really enjoy the sets in the LEGO Architecture series, and I am especially excited by the upcoming “Trevi Fountain” set. Rather than simply wait for the set to come out, I wanted to get a sneak peek at the build by trying to build part of the model without a list of parts or instructions. I also wanted to see if there are any rare or expensive parts hiding in this set.

To be clear, I never intended to finish the entire model. Even though I have a significantly enhanced LEGO Architecture Studio set, I doubted that I would have all the bricks that are needed. I just wanted to explore some of the interesting parts of the model, especially the half-stud offsets that create a lip around the top section of the building facade.

I started by building the base.

The first step I took was to try and determine the dimensions of the base. I did this by counting studs wherever possible, or by guessing based on the width of other objects. This photo ended up being incorrect, the correct dimensions are two-studs narrower in the back, for a total of 26 studs wide and 18 studs deep. (For comparison, The UN Headquarters is also 26×18, and The White House model is 28×18.)

This section also seems to use a ton of 87580 – 2×2 Jumpers, and I couldn’t figure out how to get some of the offsets without also using part 89737 – Tile 1×3 Which was also annoyingly omitted from the Architecture Studio set.

This is where I stopped… (Please ignore places where I used bricks of the wrong color.)

I continued down the facade, struggling a bit to achieve the appropriate half-stud offsets to align the windows with the obvious front-facing 1×6 tile. It looks like you will use at least 12 more of 87087 – Brick, Modified 1 x 1 with Stud on 1 Side to attach those front-facing tiles, so I expect that part will be getting cheaper on Bricklink soon. I could not achieve the appropriate offset to the window without using jumpers, and to my eye, I think we are looking at 1×2 Jumpers in Trans-Light-blue (3794 or 15573). If I’m correct, someone will be making real money on Bricklink, as it is currently a 45 cent part.

My “preview” Review

Based on the photo, this looks like it will be a great addition to the Architecture series, even though it is more of a “sculpture” than a building. My hands-on experience building sections of the model reinforced my fondness for the design. The model has very fine details which are expertly rendered. I didn’t explore the sculptural forms in the fountain, but I think they are well done, especially given the relatively small scale. Speaking of scale, this is a pretty large model for the Architecture series. I think it will be about the same size as Villa Savoye, although I hope they follow the precedent of the UN Headquarters and give the set a very low price per part, especially given that many of the parts are small.

Further, based everything I can see in the photo and everything I could guess based on building part of the model, I think this is going to be an extremely popular set for people to buy just for the parts. With so many white and clear bricks, it looks like a perfect addition to a growing “Architecture Studio” set for free-form creative architectural modeling.

Speaking of which, check out my LEGO Architecture 30-day Challenge. I built 30-different projects in about 30 days. They run a broad spectrum, and some of them are really cool!
